So I was working on this Windows Communication Foundation tutorial. The tutorial came as a pre-existing solution that you would update via WCF tasks. I'd successfully done the C# version after many attempts. Most of my problems stemmed from typos during the tutorial. Then came the VB version of the tutorial. Well, there actually wasn't much VB or C# in the labs so I can't use the excuse that I work mostly in C#. That sucks.
So what was the error? I kept running the lab and got an error that the Internet endpoint did not exist. I'd run it several times. Well as it turned out, I had a typo buried inside of the app.config file. A quick Find for the errored address allowed me to pinpoint the error of my ways.
Sometimes you just can't beat a good quick search of your project. And so, being your own spelling police really can save the day.
